Semiconductor Photocatalysis: Quantised CdS-catalysed Photoformation of 1-Benzyl-1,4-dihydronicotinamide (BNAH) from 1-Benzylnicotinamide (BNA+)

Freshly prepared CdS suspensions (CdS-0) consisting of quantised particles and their loose aggregates catalyse the photoreduction of 1-benzylnicotinamide (BNA+) in water under visible-light irradiation using triethylamine (TEA) as a sacrificial electron donor.Isomeric dimers of (BNA)2 are also found as one-electron reduction products from BNA+, whereas the photocatalysis of commercially available CdS powder (Aldrich, CdS-Ald) leads only to the formation of the dimers.The formation of cadmium metal (Cd0) on the lattice is indispensable for the photoformation of BNAH, suggesting that the eventual two-electron reduction on irradiatio n of CdS-0 with TEA in water, should proceed through hydrogen atom transfer from Cd0-H formed on the lattice of CdS-0.

Selective H2 and CO production with rhenium(I) biscarbonyl complexes as photocatalyst

Rhenium(I) biscarbonyl complexes with two phosphine ligands photocatalyzed not only CO2 reduction under CO2 atmosphere but also H2 evolution under Ar. The reductant 1-benzyl-1,4-dihydronicotinamide (BNAH) worked only as a one-electron donor, and it was quantitatively converted to its corresponding oxidized dimer (BNA2). The photocatalytic reactions required addition of a base such as triethanolamine, because deprotonation from the oxidized BNAH (BNAH?+) is essential for the suppression of the back electron transfer from the reduced rhenium(I) complex to BNAH?+. 1H, 13C, and 31P NMR studies under vacuum or 13CO2 atmosphere indicated that the rhenium(I) complex is relatively stable under the CO2 reduction conditions, but it is converted to some other complexes under the H2 evolution conditions.

Semiconductor Photocatalysis: Effect of Light Intensity on Nanoscale CdS-Catalyzed Photolysis of Organic Substrates

The relationship between light intensity and product distribution in semiconductor photocatalysis was investigated by using nanoscale CdS microcrystallites (CdS-0) as photocatalysts, triethylamine (TEA) as the electron donor, and either aromatic ketones, electron-deficient alkenes, or 1-benzylnicotinamide (BNA+) as substrates.In the case of the ketones and BNA+, the yield of their respective one-electron reduction products, pinacols and the dimer, (BNA)2, increases with decreasing light intensity.When alkenes are employed in the CdS-0 system, cis-trans photoisomerization always occur regardless of the light intensity.The kinetics for the photocatalysis of the alkanes and the measuement of the inital formation rate of active lattice Cd atoms (Cd0) (which act as catalytic sites for two-electron-transfer reductions) reveal that Cd0 formation is proportional to the square of the relative light intensity, Ir2.The chemoselectivity in the photocatalysis using nanoscale CdS should be affected by the quantity of the Cd0, whose formation strongly depends on the light intensity.

Photochemical CO2 Reduction by an NADH Model Compound in the Presence of 2+ and 2+ (bpy=2,2'-bipyridine) in H2O / DMF

Photochemical conversion of CO2 to CO and COO- was achieved by using an NADH model compound, 1-benzyl-1,4-dihydronicotinamide (BNAH), as an electron donor in the presence of 2+ (bpy=2,2'-bipyridine) and

Redox-Photosensitized Reactions. XIV. Photochemistry of 4-Alkylated NADH Models, 1-Benzyl-4-(1-hydroxyalkyl)-1,4-dihydronicotinamides

There were investigated photochemical behaviors of 4-alkylated 1-benzyl-1,4-dihydronicotinamides (1a-c) having R1R2C(OH) as the substituent (a: R1=Ph and R2=H; b: R1=Ph and R2=CF3; c: R1=p-NC-C6H4 and R2=H).The direct photolysis of 1a-c gave R1R2CO and the dimers of the dihydronicotinamide (BNA) fragment along with a minor amount of 2, being thus interpreted in terms of the homolysis between the R1R2(OH) and BNA moieties.In the 2+-photosensitized reactions, it is suggested that 1a-c+. was generated as a key intermediate by electron transfer to excited 2+, undergoing a bond cleavage to give R1R2CO and BNA. dimers.In the case of 1c, however, R1R2CH(OH) was formed, being attributed to a product from 1c-. that is formed by electron transfer from + to 1c.
